United States Antimony announced the wet commissioning of its critical mineral flotation mill located in Radersburg, Montana. The Company will celebrate this significant milestone with a Rock Breaking and Ribbon Cutting Ceremony, July 7, from 11:00 a.m. to 2:00 p.m. MST at 161 Keating Gulch Road, Radersburg, Montana, with the Governor of Montana in attendance. Following the $4.75M acquisition of this facility in January of this year and the subsequent ~$2M capital expenditures for specific equipment upgrades, refurbishments, and a new laboratory, the facility is now ready to come online and process the initial ~800 tons of antimony ore mined last fall from the Company's Stibnite Hill operations in Thompson Falls, Montana. The Radersburg Flotation Mill will start production once the laboratory is fully commissioned to allow for process and product control. The ~$1M cost to build a new laboratory features full sample preparation, a 3-kilowatt XRF, fire assay, and wet chemistry capabilities with all newly acquired equipment. Full commissioning of the laboratory and subsequent concentrate production from the mill is planned for some time in mid-July. The Stibnite Hill mine is currently producing raw antimony ore for future processing. This midstream asset is a cornerstone in USAC's fully vertical integration strategy, enabling the Company to upgrade antimony-bearing material from its Montana and Alaska mining operations into high-grade concentrate suitable for downstream smelting allowing antimony metal, trioxide, and trisulfide production. This additional throughput will enhance USAC's ability to fulfill its $245M, sole-source Department of War contract for Military Specification antimony metal, as well as its commercial obligations for fire retardants and other products, at an accelerated pace.
